Western Digital rolls out 320GB Passport external drive

Last month, Buffalo Technology announced what they claimed was the world’s largest portable external hard drive. Now, Western Digital has matched Buffalo’s offering with a 320GB version of its Passport portable hard disk drive for consumers on the move.

Weighing in less than five ounces, this 2.5-inch drive works without an external power supply – it’s powered by the USB interface – and delivers 480Mbps transfer speeds. It comes bundled with Google software, WD Sync software to make data synchronization simpler, and 128-bit encryption just in case you misplace your drive. If you're looking for portable backup solution with maximum capacity, at $229, this is a great option.
